You fall asleep to a bedtime story. Twenty minutes later it finishes, the room goes silent, and you're awake again. sndflo fades the narration out and keeps your sound mix playing — all night, or until your timer runs out.
Try it now — free No app store. No credit card.Nothing to install. Tap play, add a layer or two, and hear what it does. (Rain and brown noise are loaded to start.)
The story works. You're drifting, barely following the words, right at the edge. Then it ends.
The narration stops, the room goes quiet, and the silence is loud enough to pull you back up. Or you drift off fine and a car door slams at 2am with nothing there to cover it.
Most sleep apps treat the story as the product. The sound underneath it is set dressing that disappears when the track is over. If you want white noise after, you have to open a second app — and by then you're awake enough that it doesn't matter.
The mixer, binaural beats, timers, and saved mixes are free — not a ten-minute preview, enough to actually use every night.
The mixer here is free to use. The full sound library is a one-time $19.99 unlock in the iPhone app — not a subscription; you buy it and it's yours. (Most sleep apps run roughly $50–70 a year.)
sndflo runs in your browser, so there's no app store download and no platform fee baked into the price.
On iPhone, add it to your home screen before you use it overnight — Safari stops audio when your screen locks, and adding sndflo fixes that. Tap Share, then Add to Home Screen. One tap, and it plays until morning.
Yes. The narration fades out and your sound mix continues — through the night, or until your sleep timer runs out.
Yes. Every sound layers independently with its own volume slider. Airplane cabin plus box fan, rain plus thunder, brown noise plus a campfire — whatever works for you. Save your favorites and load them with one tap.
No. sndflo runs in your browser. You can add it to your home screen so it opens like an app, but there's nothing to install from an app store.
Yes, once you've added it to your home screen. In a regular Safari tab, iOS stops background audio when the screen locks — adding sndflo to your home screen fixes that, and it takes one tap.
Yes. Sounds download to your device the first time you play them, then play with no connection and no delay.
The mixer, binaural beats, timers, and saved mixes are free. The full sound library is a one-time purchase. There's no subscription.
